We always get a lot of questions on this topic. There are several things which are not permitted. These primarily involve political and/or nationalistic messages on clothing and accessories such as: pins and chains with Celtic symbols, boots with white laces, ties and suspenders. Flags and soccer shirts are only allowed if they concern a country. Soccer merchandise is forbidden. 

There are also items which are not described here and for this reason, we check each visitor individually on their clothes.
